How to not have a battle failure.

[player 2]

I’ve been having trouble ever since I got this game. The game doesn’t give many direct instructions meaning I have trouble guessing what to do next after every new thing I come across. What I really want to know now is how to not fail any of the missions! I have tried every thing. Even searching the web and no-one I’ve talked to so far knows how to succeed. If any on knows please help. Thanks to anyone that replies.
